COMBINATION IPA-BLOCK.

Application filed July 19, 1928. Serial No. 293,921.

This invention relates to certain new and useful improvements in combination padlocks and has for its primary object to provide a padlock in which one long leg of the shackle extending into the lock casing is engaged and retained therein by a locking pin con trolled in its sliding movement by rotatable disk tumblers operated by the provision of a pair of manually shiftable handles extending through slotted openings in the lock casing.

A further object of the invention is to provide a combination padlock of the above type in which there is provided a plurality of disk tumblers having angle lugs projecting from the peripheral edge thereof with a handle carried by two other disk tumblers to effect rotation thereof and also rotation of the other tumblers for disposing all of said tumblers in positions to permit sliding movement of the shackle engaging pin for disengagement from the shackle to permit opening of the lock.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawlugs and claimed. I

Figure 1 is a side elevational view of the combination padlock constructed in accord,- ance with the present invention, showing two operating handles for disk tumblers w1th1n the lock casing;

Figure 2 is an edge elevational view of the lock showing the slotted openings in the side wall through which the tumbler handles extend same is herein illustrated as comprising a circular casing having a bottom wall 1 an annular wall 2, and a top wall 3, the top wall 3 being retained in position on the lock casing by the center bolt 4. The annular side Wall 2 of the lock casing is provided with a pair of slotted openings 5 and 6 through which operating handles extend as shown in Figure 2 and said annular wall is further provided'with openings for the passage of the short and long legs 7 and 8 respectively of the shackle 9, the leg 8 of the shackle having a notch 10 formed in one side to receive the locking bolt or pin of the combination lock mechanism.

The detail parts of the lock mechanism are shown relatively positioned in Figure 3, while the assembled formation thereof is illustrated in Figures 4; to 7 The combination lock mechanism comprises a sliding tumbler plate 11 of the form best illustrated in Figure 3 having a slottBd opening 12 therein adjacent one end through which the bolt 4; extends, the opposite endsof the sliding tumbler plate 11 having an end opening slot 18 that straddles the headed retaining pin 14 as shown in Figure 7, this end of the plate 11 being slidable, beneath the block 15 projecting inwardly from the adjacent portion of the annular side wall 2 of the lock casing and with which block the leg 8 of the shackle is engageable. A perpendicular pin 16 carried by the tumbler plate 11 is adapted to be received in the recess 10 in the shackle leg 8 and also in the vertical slot 17 in theinner end of the block 15 for locking the shackle in the casing as shown in Figure 4. A notch 18 is formed in one side edge of the tumbler'plate 11 to re ceive one end of the leaf spring 19 that has its outer end secured as at 20 to the inner face of the annular wall2 as shown in Figure '6, the spring 19 tending to move the tumbler plate 11 and pin16 carried thereby away from the block 15 and shackle leg 8 to its releasing position. The opposite side edge of the tumbler plate 11 carries a perpendicular finger 21 that is adapted to be engaged by a s tumb r lua- A disk tumbler 22 has a Central opening 23 ceived on he o 4: h a Pe iph ra ne h -2 of a ze o r ceiv the pin 16. An arm 2. Proje t from he peripheral e e o t d sk um le w th the outer nd teeof bent upwardly to form a tumbler lug 26. The tumbler disk 27 has an opening 28 received on the bolt 4 and is engaged with the tumbler disk 22, one side 29 of the tumbler disk 27 being cut away or reduced to provide a clearance for retracting movement of the pin 16 so that the disk 27 may rotate upon the bolt 4 when the pin 16 is received in the side notch 24 of the tumbler disk 22. A tumbler arm 30 projects from one side of the tumbler disk 27 while an oppositely disposed arm 31 that projects from the other side has the outer end thereof bent upwardly to form a tumbler lug 32. A handle 33 carried by the peripheral edge of the tumbler disk 27 extends through the slotted opening in the side wall of the lock casing with a block 34 on the end thereof eXteriorly ofthe lock casing to facilitate operation thereof.

A disk tumbler 35 with the central opening 36 is then placed on the bolt 4 and has a peripheral notch 37 to receive the pin 16, the disk 35 also carrying a relatively short arm 37 projecting from the peripheral edge thereof with the outer end bent downwardly to form a tumbler lug 38. The disk tumbler 39 having the central opening 40 is then placed on the bolt 4 and is likewise provided with a peripheral notch 41 and a relatively long arm 42 having the outer end bent upwardly to form a tumbler lug 43. A leaf spring 44 is secured intermediate its ends to the inner face of the annular side wall 2 of the lock casing and has one projecting end 45 thereof engaged by the lug 43 when in the position shown in Figure 6 for holding the disk tumbler 39 in its shifted position. The disk tumbler 46 having the central opening 47 then is placed on the bolt 4 and has a peripheral notch 48 and operating handle 49 that extends through the slotted opening 6 in the casing with an operating block 50 upon its outer end.

A disk tumbler 51 having the central opening 52 is then placed on the bolt 4 and is provided with a side notch 53 and relatively long arm 54 bent downwardly at its outer end to form a tumbler lug 55 that is engageable with the other end 56 of the spring 44 to be held in its adjusted position. The top tumbler disk 57 having the central opening 58 is then placed on the bolt 4 and is provided with a peripheral notch 59 and a pair of depending tumbler lugs 60 and 61.

\Vhen the shackle leg 8 is locked within the casing, the tumbler plate 11 is under ten sion of the spring 19 with the pin 16 extending into the leg opening of the shackle and also into the vertical recess 17 of the block so that the shackle is restrained from movement, and in this position, the several tumbler disks illustrated in Figure 3, have plain edges thereof abutting the adjacent side of the pin 16 to hold the pin in its shackleengaging position and against movement by the spring 19. To release the pin 16 from the shackle leg, it is necessary to align all of the peripheral notches in the tumbler disks therewith and to accomplish this object, the handle 33 is first moved from the lower end of the slot'5 to the upper end thereof. During such movement, the handle 33 engages the tumbler lug 26 upon the disk tumbler 22 while the arm upon the disk tumbler 27 engages the depending tumbler lug 38 upon the disk tumbler for positioning the notch 24 in the tumbler 22 and notch 37 in the tumbler 35 in alignment with the pin 16. The disk tumbler 46 is then operated by the handle 49, the handle engaging the tumbler lug 43 to move the notch 41 in the disk tumbler 39 into alignment with the pin 16 with the tumbler lug 43 engaged with the spring to be so held. The handle 49 also engages the lug 61 upon the tumbler disk 57 to move the same therewith. The handle 49 is then moved toward the bottom end of the slot 6 and during such movement, the lug upon the tumbler disk 51 is engaged thereby while the arm 54 upon the tumbler disk 51 engages the tumbler lug upon the tumbler disk 57 for positioning the two notches 53 and 59 of the tumbler disks 51 and 57 respectively in alignment with the pin 16. The tumbler lug 55 is also engaged with the spring 44 for holding the same in adjusted position. The handle 49 is then moved upwardly in the slot 6 as far as the indicator 62 as shown in Figure 2 to position the notch 48 in the tumbler disk 46 carrying said handle into alignment with the pin 16. At this moment, all of the disk notches are aligned with the lockin pin 16 and the tumbler lug 32 upon the tumbler disk 27 that has the handle33 at the upper end of the slot 5 is engaged with the finger 2'1 upon the tumbler plate 11 and the spring 19 exerting its force moves the tumbler plate 11 and automatically shifts the handle 33 to the middle of the slotted opening 5, while the pin 16 moves into the aligned disk recesses. The shackle leg 8 is then released and the shackle leg 7 may be moved outwardly of the lock'casing while sliding movement of the leg 8 is limited by the pin 63 carried thereby and intended for engagement with an adjacent disk tumbler in its path of movement. The shackle is placed in a locked position by first raising the handle 33 in the slot 5 and during such movement, the arm 31 upon the disk tumbler 27 engages the finger 21 on the tumbler plate 11to move the pin 16 into the bolt notch and block slot and subsequent operation of the handle 49 and lever 43 will displace the several disk tumbler notches from alignment with the locking pin 16.
